G'day

I currently have an E34 535 rolling shell and a spare LS1 as well as a spare RB25DET. Both motors are stock and I am looking at putting one of them in the E34, gutting the shell and taking it drifting.

I have test fitted the LS1 and so far, nothing fits. The engine is way too far forward as the K frame is quite far forward and then there is another bar behind it as well as a drag link to miss as well as the steering box on the drivers side to avoid
to make the headers fit.

Haven't tried the RB25 yet but I can see the brake booster (mounted on the passenger side) being an issue with the turbo in the stock location and with the heat coming off the turbo.

I would rather run the LS1 over the 25.

To fix this I would have to chop the fuck out of the k frame and probably go custom headers ( would rather not because of cost) or potentially mount a k frame out of a VT etc. commodore as this would allow an upgrade to rack and pinion
steering as well as not having to worry about exhaust fitment, engine mounts or starter motor location.

I know doing this would change all the steering geometry but I would probably convert everything to commodore spec anyway.

What are peoples thoughts on the trade offs with this setup?

Do it right, make it an engineered street car with the LS, get bored, sell to me.

Thank :d

Sorry I can't give any other advice!

Why not chop the firewall/transmission tunnel to move the motor back?

Quick google brought up this thread.

They discuss the different options with sumps and how to get them to fit.
